Description: 这是我用汇编语言写的音乐播放程序
此程序为用89c51控制 输出为 lm386 功放
本程序中有14首曲子代码 均是本人花费大量时间手工转换
本程序之所以叫key_W29C020_music+code 是因为本程序是写在W29C020芯片中的 单片机中不用写程序 W29C020是主板上的bios芯片 256k 的flash
当然 你也可以将代码烧到89c51中 -This the compilation of language I used to write music player for the use of this procedure 89c51 control output lm386 PA this procedure is 14 song code is I spent a lot of time and manual conversion of the procedure is called key_W 29C020_music code is because the procedures are written in the W29C020 chip microcontroller W29C020 do not have to write a program on the Main Board of bios chip 1058 Kb of flash Of course, you can also code decoder which reaches 89

Description: 接收单元，我们采用的原理和调频收音机原理一样。图3为接收电路，以专用调频接收模块IC1 TDA7021T为核心，经解调后的音频信号从脚输出，送到IC2 LM386作功率放大，推动耳机发声。三极管BG9018等组成高频放大级，以提高接收灵敏度。调节可调电容器C23可以改变接收频率，使其对准发射机的发射频率。-Receiving unit, we have adopted the principle and the principle of like FM radio. Figure 3 for the receiver circuit to a dedicated IC1 TDA7021T FM receiver module as the core, after demodulation of the audio signal after the output from the feet, to make IC2 LM386 power amplifier, and promote sound headphones. BG9018 triode composed of high-frequency amplification level in order to improve receiver sensitivity. Conditioning adjustable capacitor C23 can change the receiver frequency so that it fired at the transmitter frequency.

Description: LM386是一种音频集成功放，具有自身功耗低、更新内链增益可调整、电源电压范围大、外接元件少和总谐波失真小等优点的功率放大器，广泛应用于录音机和收音机之中。
LM386是美国国家半导体公司生产的音频功率放大 器,主要应用于低电压消费类产品。为使外围元件最少,电压增益内置为20。但在1脚和8脚之间增加一只外接电阻和电容,便可将电压增益调为任意值,直至 200。输入端以地位参考,同时输出端被自动偏置到电源电压的一半,在6V电源电压下,它的静态功耗仅为24mW,使得LM386特别适用于电池供电的场合。
